Often when a marriage turns sour, things not so coincidentally seem a bit — off –in the family finance department.

Yesterday, Forbes.com published an excellent article outlining 21 common red flags of financial hanky-panky leading up to divorce.

While a few of the signs of trouble apply only to high-asset families — e.g., frequent trips to countries with soft banking laws — others signal shady maneuvers that are common at all income levels.

If you notice that your spouse’s behavior has changed when it comes to earning, spending or borrowing money and, at the same time, all is not blissful on the home front, make some notes and do a reality check of your own. Even if you find nothing amiss, the clues you record might come in handy to your divorce lawyer further down the road.

And if your spouse suddenly decides it would be a good idea to re-mortgage the house to pay off cars or business and credit card debt, by all means take the temperature of your marriage before signing on the dotted line. The bigger the hurry, the more reason to slow things down.
